Mosquito-borne disease is the biggest threat to Hawai‘i’s remaining native forest birds, of which more than half are threatened or endangered. Currently, disease-carrying mosquitoes are unable to move into colder high-elevation forests, but as the islands warm due to climate change, mosquitoes are steadily moving into the last native bird strongholds. Mosquito suppression efforts are planned for three Hawaiian Islands, however, there is currently no monitoring program to assess the effectiveness of those efforts. To address this pressing need, this project will develop new monitoring tools and protocols to provide managers with information about changes in bird and mosquito numbers that are related to climate change...

Distance-power relationship data used in our automatic detection algorithm. First release - January 18, 2017 Revised - August 2018, ver. 1.1

Occupancy data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers listened for Reed-warblers during the 3-minute survey period (30 seconds of playback followed by 2 minutes and 30 seconds of observation). Observers recorded the horizontal distances of any Reed-warblers heard/and or seen, direction of the bird from the observer, and time of detection. The data set also includes covariates that may influence the occupancy of birds.

This dataset contains the point-transect distance sampling records of Hawaii Akepa collected at Hakalau Forest National Wildlife Refuge between 1987 and 2017. These data include the survey point locations, observer details, time of day, and sampling conditions during the counts. In addition, the data include the elevation and alliance level habitat classification at the survey points. Provided here in the data release is the single tabular dataset containing the project’s bird and habitat data.
